The first movie I literally ever made in my life was about two guys playing Stratego with each other. I had all my friends dressing up like the military characters in the game. So 'Battleship' is really my second board game turned movie!
I somewhere along the way became fascinated with exploring characters who are willing to put themselves into violent situations, whether it's football, hockey, boxing, being a cop, being a soldier. There's not a lot of people who are willing to put themselves into those situations.
